Microsoft always had an advantage over Google and Yahoo! because MSN Search was the default homepage for Internet Explorer on all the Microsoft computers. This will definitely send them a ton of traffic, right?

Well now Yahoo! is doing the same thing, but they are not partnering up with Microsoft. Instead, they have partnered with Acer Computers, which is one of the fourth largest computer distribution companies in the world!

Not only will Yahoo! be the homepage for Internet Explorer, but they will also brand the Yahoo! toolbar into the Internet Explorer.

Partnering with Acer Computers can extend Yahoo! to over an extra 500 million visitors. Acer Computers is also the third leading vendor of notebooks in Europe, Middle-East, Asia and Africa.

Here is a preview of the press release early this morning:

The partnership will give millions of Acer customers around the world easy access to trusted and vital services, such as Yahoo! Search, Yahoo! Mail, Yahoo! News, and Yahoo! Finance, from one of the Internet’s most trafficked sites.

Acer will preload a co-branded Yahoo! and Acer toolbar and start page on Acer PCs shipped worldwide. The co-branded start page will automatically appear when an Acer customer opens a Web browser on a new laptop or desktop computer and will offer: Yahoo! content, such as news; links to Yahoo! services, such as Yahoo! Music and Yahoo! Sports; the Yahoo! Personal Assistant, as seen on Yahoo!’s new home page, for quick access to Yahoo! Mail, Yahoo! Messenger and Yahoo! Local information; direct links to specific Acer customer services; and an Acer module for up-to-the-minute information on Acer news and products. The start page will reflect the look and feel of the new Yahoo! home page in order to provide Acer customers with the best and most innovative portal experience.
